 ### Common-Mode Stability
 
-In a pseudo-differential power amplifier, often capacitive neutralization is used to to neutralize the gate-drain capacitance of the transistors. This enhances gain and differential stability, i.e., the stability we looked at above when the inputs are driven with a differential signal.
+In a pseudo-differential power amplifier, often capacitive neutralization is used to to neutralize the gate-drain capacitance of the transistors. This enhances gain and differential stability, i.e., the stability we looked at above when the inputs are driven with a differential signal. However, through that measure we have increased the gate-drain capacitance in common-mode which gets exacerbated through the miller-effect. Thus, the chance of common-mode instability increased.
 
-The signal at the gates can have a common-mode component, however, meaning that it is the same on both sides. This can occur because of the balun not being balanced or common-mode noise. Hence, common-mode stability needs to be assessed.

+Below you see the setup to test common-mode stability and the equations to evaluate the data in the ADS data display. The mu parameters indicate that this circuit not unconditionally stable for common-mode signals.
